1. FUNCTIONS AND CONFIGURATION

1.5 System configuration

(1) When A B Z differential input interface unit (MR-J2S-CLP01) is used
The A B Z differential input interface unit (MR-J2S-CLP01) converts external ABZ phase pulses
into a position feedback signal that can be used for serial communication.
Full closed control is enabled by connecting the output of the MR-J2S-CLP01 to the servo amplifier
encoder connector.
CAUTION
System configuration example 1 (when ABZ pulse train-specified linear scale is used)
SSCNET controller
Encoder signal
Note 1. A linear scale without Z phase cannot be connected.
2. No compatibility with an absolute position detection system.
System configuration example 2 (when ABZ phase pulse train-specified rotary encoder is used)
SSCNET controller
Encoder signal
Note 1. A rotary without Z phase cannot be connected.
2. No compatibility with an absolute position detection system.
3. In this example, full closed control cannot be performed if there is no stock (work).
When the MR-J2S-CLP01 is used, a linear scale without Z phase cannot be
connected. Use a linear scale that has the Z phase.
